HENRY SPRINGER, OF BRADY, MICHIGAN.

IMPROVEMENT IN FERTILIZING ATTACHMENTS TO SEED-SOWERS.

Specication forming part of" Letters Patent No. 141,606, dated August 5, 1873; application iiled A October 11, 1872.

To all whom it may concern:

Be it known that I, HENRY SPRINGER, of Brady, in the county of Kalamazoo and State of Michigan, have invented a new and useful Improvement in Fertilizin g Attachment to Seed-Sewing Machines; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon and being a part of this specification, in which- Figure l is a perspective view, and Fig. 2 a longitudinal and sectional view, of the attachment for sowing plaster, lime, or other pulver- 'ized fertilizers.

Like letters refer to like parts in each'gure.

The nature of this invention relates to an improvement in the construction of seed-sowers, by the attachment of a device for sowing any pulverized fertilizers, driven by the same power which operates the seed-sower; and the improvement is more especially designed as an addition and improvement to the seed-sowing machine, for which Letters Patent were issued to me by the United States on the 30th day of March, 1869, and numbered 88,525. The invention consists in certain details of construction, as will be fully described hereinafter.v

In the drawings, C is the ground or driving wheel. A is the pulley attached to spokes of the said wheel. H is a belt connecting said pulley to the crank-pulley B, which is connected by a rod to the bell-crank E, which operates the lever G, thereby imparting a reciprocating motion to the rope D. Fis my seed-box; andthe construction and operation of all the foregoing named and lettered parts are fully described in my said Letters Patent.

I will now describe my additions and improvements.

K is a V-shaped box, the lower edges of the sides of which do not come quite together, leaving room for the serrated bar L to have a free reciprocating motion for the purpose of preventing the plaster or other fertilizer from packing or choking. The opening between the bottom edges ofthe box may be increased or diminished by means of the set-screws M, which are adapted to force the sides together. A reciprocating motion is given by means of the rod N connecting said bar with the bellf crank E.

In the drawing I show a detached and enlarged section, showing the spring-bearing to the axle.

P is a stirrupboX, within which the aXle ofthe driving or ground wheel rotates. Between the ends of the axle and the barrow frame, which sustains the operating parts of my machine, and within the stirrup-boX, I interpose spiral or other suitable springs, for the purpose of giving greater steadiness to the operating parts when the machine is being driven over uneven or stony ground.

What I claim as my invention, and desire to secure by Letters Patent, is-,

The fertilizer distributing attachment to seed-sowing machines herein described, consistin g of the V-shaped box K, serrated bar L, connecting-bar N, and bell-crank E, arranged upon the frame in front of the seed-sowing box, and operated by the power that actuates the sower, all constructed and arranged substantially as specified.

HENRY SPRINGER.
